r APPARATUS FOR TREATING FABRICS.

Application filed January This invention relates to improvements in apparatus for treating fabrics, such apparatus bein used in dry cleaning plants for removing ry cleaning agents from the fabric and for freshening or renovating the same after the d cleaning operation.

One object of t e invention is to provide im roved apparatus of this character within whlch the fabric material, such as wearing apparel, is first dampened by a steam cur rent, one important purpose of the steam being to minimize static efi'ects in. the apparatus and reduce fire hazard by humidif mg the air during the first part of the eye e of operation when the static effect is usually a maximum, and in which apparatus the material is next subjected to a current of heated air to first remove the moisture and volatilize the cleaning fluids and then to deodorize the material, and in which apparatus the material is finally subjected to a current of cold or fresh air for cooling and freshening purposes.

A further object of the invention is to provide improved control means for the apparatus, which means is entirely automatic in character so that after the operator has started the machine he is free to-do other work until the material has been sufiiciently cooled and is ready to be removed. More specifically, the invention aims to provide control means which effects the introduction of steam into the machine for a predeten mined period, then terminates the steam supply and effects the fiow of heated air through the machine to remove the moisture and volatilize the cleaning fluids from the work and after said removal continues said flow for a predetermined period to deodorize the ma.- terials; and which finally effects the flow of cold or fresh air through the machine .to cool and freshen the materials. The invention also provides a signal system so arranged that when .the materials have been cooled to a predetermined degree an audible or other suitable signal is automatically produced, notifying the operator that the work is ready to be removed, and during the flow of heated and cold air automatically produces visible or other suitable signals to advise the operator as to what is taking place in the machine. a

For purpose of illustration, the drawings show apparatus of the tumbler type, its particular construction and arrangement being largely immaterial. The machine here illustrated includes a suitable hollow frame or.

casing 1 in which is adrying chamber 2 con within which the fabric or clothing is tumbled or agitated b rotating the drum. For this purpose, the rum is turned first in one direction and then in the other by a suitable source of power, such as an electricmotor 4 having its'driving shaft connected by suitable gearing 5 to theshaft 6 of the drum.

Communicating with the drying chamber through an opening 7 is an air chamber 8 within which is a fan or blower 9 driven by belt 9 from motor 9 and having its suction side connected with the air chamber 8 and its outlet communicating with a passage.

10 opening to the atmosphere at one end of the machine. The fan motor may be a constantly rotating motor controlled by a separate switch and circuit, or may be in circuits controlled by .or in connection with the circuits for other part of the apparatus, as

copending application hereafter referr to. Atmosphericair entering the easinginlet opening 12 at the opposite end of the machine flows into the heating chamber- 13 in which is a suitable heating device, such 'fan through the casing outlet passage 10.

of the tumblercasing is the At the to ii air inlet 20 which is covered cold or fres during the flow of steam ma heated air pivoted armature '39.

, :;y a damper 21 adj ustably mounted by means of a set screw 22 upon a shaft 22 having an arm 23 connected by a link 24 with a pivoted, manually operable control lever 25. When said control lever is held in its lowermost position, as in Fig. 1, by the latch mechanism hereinafter described, the damper 21 covers the cold air inlet. When the. latch mechanism is actuated to release the control lever, the latter is pulled to its uppermost osition by a spring 26, thereby rocking t e shaft 22, swinging the damper downwardly to open the cold air inlet and closing the passage 15 through which heated air passes into the drying chamber.

The latching mechanism for control lever 25 is arranged within a suitable casing 30, secured to one end wall of the tumbler casing. Journailed in the lower portion of this latch casin is a shaft 31, normally tending to turn in a clockwise direction under the action of a spring 31, and upon which shaft are fixedly mounted latch arms 32 and 33. Arm 32 extends through a vertical slot 33 in the front wall of the latch casing (Fig. 10) and has abifurcated forward end to receive the hook extension 25" of control lever 25. Latch arm 33 is provided with upper and lower shoulders or abutments 35, 36 for cooperation with a roller 37 on the depending trigger arm 38 of a Said armature cooperates with a coil 42, being normally held away from said coil by a spring 43. When the latching parts are in'the position shown in full lines, Fig. 10, the control lever 25 is held or latched in its lower position, Fig. 1, by the engagement, of its hooked extension 25" in the recess in the end of'latch arm 32 which, to ether with the latch member 33, is held in t e position shown by the en age ment of the armature trigger 38 with atch arm abutment 35-. The latching parts ma be released by energization of coil 42, whic attracts the armature 39 and moves the roller'37 thereof outwardly and away from abutment 35, thereby permitting latch members 32 and 33 to be raised by'the s ring 31" (Fig. 10) and control lever 25 to be raised 7 by the spring 26 (Fig. 1), thereby shifting the damper21 from hot air to co air position. Suitable means may also be provided for tripplng the parts manually, such as a opening 16 into the drying c amber fin er lever 44 pivoted-on the latch casing an having a thumb piece 45 exposed above the same and a lower arm lying infront of the armature. Assuming the latch to be released with the roller 37 lying against abutment 36, as in dotted lines Fig. 10, and coil .42 to be tie-energized, the armature 39 and its attached arm 38 are now sub'ect to the influence of spring 43, so that w on lever 25 is depressed manually its hooked extension 25 enters the recess in arm 32 and pulls said arm downwardly until the roller 37 snaps in behind the abutment 35, the parts then being locked or latched in the position shown in full lines F lg. 10 until again released.

In the latch casing 30 at one side of the coil 42 is an insulating support 50 carrying a coil 51 with which cooperates an armature 52 pivotally mounted intermediate its ends on a bracket 53 carried by the insulating support 50. This armature is held away from coil 51 by a spring 54. The upper end .of said armature carries a contact 55 adapted for cooperation with a stationary contact 56 electrically connected to the coil 42 and carried by a bracket 57 secured to the upper end of the insulating support 50. Mounted upon the lower end portion of this insulatmg support below the magnetic coil 51is .a set of five contact fingers. The first three time interval, to wit, the steaming and deodorizing operations. The machine is therefore provided with timing mechanism includlng two like timing devices, one for each of said operations. In Fig. 3 let it be assumed that the timer A at the right is for the steaming operation and the timer B at the left is for the deodorizing operation. Exce t as hereinafter noted description of one t ereof will therefore suflice for both.

Each' timer includes a stationary circular conducting segment 70 having a gap 71 and mounted upon an insulating base 72, said segment co-operating with a movable contact 73 carried by a conducting arm 74 havmg a ring portion 75 co-operating with a stationary brush 76. Said ringsaiid arm portions are mounted to turn with-re shaft 7 rovided at one end with an operating kno 78 and at the other end with a gear 79 ada ted to be driven by a gear 80 loosely rotata 1e on the shaft 81. The two gears 80 for the two timing devices, one at each side of the timer casing shown in Fig. 3, are adapted to be individually and selectively driven by suitable driving mechanism, such as by a connection to the motor 4, which reversely rotates the drum 3. In the present instance the timers areactuated .by said motor by means of a connection to the drum shaft 6, said connection including an eccentrically arranged shaft pin 82 connected by a rod 83 to a reciprocatable slide 84 provided with a ielding pawl 85. Said pawl cooperates wit the teeth of a ratchetfwheeb 86 on a shaft 87 having a pinion 88 mesh t ing with'two gears 89, one connected to r0- tate each of the shafts'81, before referred to. Therefore, said shafts 81 are continually rotated in one direction when the drum is in operation, and regardless of reversals of rotation of the drum.

Suitable means is provided to connect either of the two timing devices to be driven by its shaft 81 when desirable. The means shown for the purpose is an electromagnetic clutch, comprising a coil 90 rotatable with the shaft 81 and having proper electrical connections through the conducting rings 91 and brushes 92, and which coil co-operates with an armature in the form of a disk 93 having free but relatively small longitudinal motion on shaft 81 and provided with pins 94 entering openingsof the gear 80. When the electro-magnet1c coil is energized the armature 93 is, attracted toward said coil and is caused to turn-with it and with shaft 81, thereby driving gear 80 and pinion 79 and causing the arm 74 to move the contact 73 over the segment 70. Themotion of both ofthe arms 74: when so driven, is in the clockwise direction, Fig. 3.

To set either of the timers, the knob 78 is turned in the counterclockwise direction, Fig. 3, thereby loosely rotating the pinions 79 and 80 and armatures 93. The parts are turned an amount havin a definite time value, as predetermined y the s ecd of shaft 6 and as indicated by the dia 95 also carried by shaft 77. When adjusted, the parts will stay in the position to Wl'l1Cl'l 3.d

justed until the clutch is coupled by energization of the coil 90, whereupon rotation of the drum shaft 6 through pawl 85 will turn the ratchet 86 anddrive the gears toturn arm 74iand ultimately restore the parts to initial or zero position with 73 opposite the gap 71.

Preferably means is provided to produce a quick break in the circuit when the gap 1s reached. For this purpose the drawings show a pin 96 havinga V head 97 urged yieldingly by the spring 98 against the periphery of the dial 95, which is provided at one point in its. erip'hery with a notch or recess 99. Said pin is mounted to slide crosswise in a stub shaft 100 loosely journalled to turn in, the casing. Fig. 6 shows the the contact parts in the zero position of the timer, with the in 96 inclined toward the left and its he'a urged yieldingly by the sprin into the recess 99. When the dial is turne with the shaft 77 to set the timer the first increment of motion of the dial in the counterclockwise direction moves the notch 99 to thetright in Fig. 6, carrying with it pin 96 afr'diturnin the dotted line position Fig. 6, with the head of the in ressed against the peri hery of the dia peration of the timer by snaft 6 returns the dial to its original position and during the last increment. of its return motion'the recess. 99 comes into range of the pin 96 which enters said recess and with the pin passes over dead center position and finally subjecting the dial to the expanding erefore osition,

provided with suit passing of contact 73 rom the the same with the shaft 100 to able means for introducing a suitable moi's tening agent, such as live-steam, to the air circulating system, said steam preferably entering the air circulating system before the air current reaches the work being treated. The purpose of this live steam is to keep moist the air laden with gas volatilized from materials previously subjected to a dry cleaning operation andthus reduce or eliminate fire hazard. The tendency to produce minute arcs by static effects is also reduced or eliminated and the steam assists in freeing lint from the garments. The means shown for introducing steam comprises a steam supply pipe .103 connected by Way of a valve 104 with a pipe 105 extending into the heating chamber, such as near the top thereof, where said pipe is perforated as at 106 to form jets. Valve 104 is normally closed,'but is opened by energizatlon of an electromagnet, the coil of which is indicated at 107.

Certain operations ofsthe machine, such as the shift ng of the damper 21 and the sounding of an alarm at the conclusion of all operations, are preferably governed by thermostatically controlled means, such as the thermostatic element or member 110 extending into the air circulation system at a suitable point, preferably at a point beyond the drying chamber, and which element is connected to and actuates the movable current conductingv arm 111 of a thermostatic controller, said arm co-operating with two individually adjustable contacts 112, 113', the first of which'is for the maximum temperature and the second of which is for the minimum temperature as will appear.

Referring to the diagram, Fig. 11, 115

indicates a lamp, the illumination of which occurs when hot airis being circulated, while the lamp 116 indicates the circulation of cold air. 117 represents a suitable signal device such as a buzzer, bell or the like, I

open switch 117 in a circuit to the audible signal 117. The machine is started by energizing the fan driving motor through its main switch and'particularly by depressing the starting button 118, Fig. 11. The starting circuit is as follows: From L byway of wire 119 through the coil of the relay 120, thence through the stop buttons 121, 121, start button 118 and by way of wire 122 to L Energization of coil 120 closes the two sets of normally open contacts 123 and 124. Closing of contacts 124 completes a maintaining circuit for the coil 120, from the stop button 121 by wayiof wire 125, the series coil 126 of a contactor and contacts 123, while contacts 123 also complete the motor circuit to and through the drum controller indicated generally at 127, and whichmay be driven by any suitable driving mechanism, such as a pilot motor or the like. Said controller by steps reduces the resistance in the motor circuit, finally throwing it across the line and on the second half of its cycle reverses the motor circuit and again varies the resistance so that the effect of the controller is as usual to produce rotation of the motor first in one direction and then in another to thereby rotate the drum 3 reversely in opposite directions. Drum shaft 6 of course rotates reversely in opposite directions but regardless of the direction of its rotation its effect upon the pawl 85 which actuates the timing mechanism is the same. It has been assumed for example that the timer A for the steam operation is set for, say five minutes, and the timer B which controls the de-odorizing operation, is set for, say, six minutes, by rotation of the timer shafts 77 to their proper positions, and that the adjustable maximum and mini mum contacts 112, 113 of the thermostatic controller have been set for definite desirable maximum and minimum temperatures. Since the contacts 124 are closed to complete a circuit'through the stop buttons 121, 121, a circuit is completed from L by way of wires 128, 129 to the contact 59, which is bridged to contact by bridge 62, thence through the lamp 115 and by wire 130 to the stop button 121 and thence to L. Lamp 115 is therefore illuminated and indicates circulation of hot air. The damper 21- is in the position shown in Fi 1 and atmospheric-air is drawn in at t e bottom of the machine, passed throu h the heater and thence to the drying c amber and is then discharged by the fan to the atmosphere. At the same time a circuit is completed from wire 128 by way of wire 131, and timer A through the coil 107 which opens the valve 104 and causes steam to be supplied to the air current to moisten the air current in the drying chamber. Likewise the clutch actuatin A is energized, t ereby closing its particular magnetic clutch and connectin the timer A, controllin the steam s'uppfy, to be driven by the sha t 6.

The steaming operation proceeds for a definite period governed by the setting of the timer A, five minutes in this instance, and at the end of said period the circuit through the timer A is quickly broken by the spring pin 96, Fig. 6, thereby de-energizing coils 107 and 90 cutting 01f the supply of steam and de-energizing the clutch operating coil and terminating the drive of the timer A, which remains ready for an other setting.

The second step or phase of the operation now proceeds, to wit, the drying operation during which atmospheric air heated in the heater is circulated over the clothes as before, but without a supply of steam. This operation continues until the last vestige of moisture or cleaning fluid or substance is removed from the clothes, whereupon the temperature of the air current leaving the drying chamber begins to rise until finally it reaches a maximum, causing the thermostatic element 110 to produce movement of the arm111 suiiicient to reach the maximum setting of timer B has also completed a circuit from the segment of said timer by way of wire 135 through the coil 51, thereby opening the normally closed contacts 56,

55 and opening the circuit through coil 42 of the latchymechanism, so as to maintain the latching parts in their latching positions,

Fig. 10. a

With the parts inthis position, the third step or phase of the operation proceeds, to wit, the de-odorizing operation, durin which hot air is circulated through the wor coil of the timer" .e-ner 'izing coil 90, so that the magnetic re-- in the machine for a period determined by the timer B, six minutes in this particular instance. When this period is concluded the controlling circuit through timer B: is opened by the passage of its contact 73 ed from its segment 70, thereby de-energi'zing coil 133 and opening contacts 134 and declutch is uncoupled. The timer mains at rest ready for another setting. Opening of the circuit through timer also tie-energizes the circuit through coil 51, thereby permitting the circuit through coil- 42 to be closed at the contacts 55, 56, so that the latching parts are tripped by the armsture 39 and the arm or lever25 is released for operation by its spring 26. At the same time rotation of the shaft 31 by its spring 31 shifts the bridging contacts 61, 62, 66

to the position shown in Fig. 12 in which position the circuit from 59 to 60 is broken and new circuits are established between contacts 58, 59 and 64, 65.

Movement of the lever 25 shifts the damper 21 to the. cold air position, opening the fresh or cold air inlet 20 and closing the, passage 15.

The circulation of hot air during the deodorizing period, terminated in the manner just described, has for its effect the removal from the work of any slight traces of odor such as might cling to. the work as the result of the use of detergents, dry cleaning agents or any other materials.

When the bridging contacts 61, 62, 66 are shifted to their second position, just referred to, thecircuit through the hot air lamp 115 is interrupted and anew circuit is est-ab- I 'lished across the contacts 59, 58 through the 'cold airlamp 116, the illumination of which indicates the'flow of fresh or cold air over the work. At the contacts 64, a circuit is established through the'now closed door operating switch 117 and through both the audible signal 117 and the coil 121'?,'but said circuit is interrupted at the thermostatic controller. When the cold air passed across the work'reduces the temperature of the air current to the desired minimum, represented by the position to whichthe minimum contact 113 is adjusted, the arm 111 of the thermostatic controller reaches contact 113 and completes a circuit through the thermostatic controller, thereby de-enerizing relay coil 120 and stopping the; machine and soundiug an alarm at the signal 117, advising the operator that the particular cycle has been completed. The door is opened, thereb openin switch 117? and stopping the 9. arm an the drum'is unloaded and .reloaded. Next, the. two .timers, A B are reset for the'desiredperiod for steaming and de-odorizing, the handle 25 is pulled down to again latch' the damper 21in hot air position, the doors-are closed and an audible signal will again the start button 118is depressed to initiate another cycle. If for any reason the operator fails to reset the dial B for the deodorizing timer the damper lever will not Fig. 12, and the circuit through the audible,

signal 117 remains complete. Such warning therefore advises the operator to set the damper lever. Neither can the machine be restarted until coil 121 is de-energized by setting the damper lever.

The cycle "of operations maybe interruptcd'at any time by depressing stop button 121 thereby (lo-energizing :all circuits. except those through the wire 128, and upon their proper positions the c cle ma be continued to its proper conc usion row the point at which it was interrupted. I

Considering the mechanism as .a whole it is practically automatic throughout, the operation requirin onlythe setting of the various parts an the initiation of the ole, which is carried out to conclusion w't out attention by the operator, who" is notified of the completion of the cycle by the audible signaL- During the cycle of operations the work is first steamed, thendried, then dc odorized, and'then cooled, the steaming and de-odorizing periods being definitelylimited to any predetermined period and the drying and cooling periods terminating when predetermined maximum and minimum temperatures are respectively reached. The net rework in the most-e cient mariner; While the invention is applicable particularly for use in .dry cleamng plants, it will be understood of course that certain features may also be used in connection with other classes depressing the start button with all parts in Y 'sult is a proper hryin and freshening of the ina way the air circulation is controlled by or in accordance with the humidity of the heated air. In other words, the humidity of the heated air has an effect upon the temperature to which the thermostatic element is sensitive and'by setting the thermostatic element to a desired maximum temperature responsive point, practically any des1red pre determined minimum degree of humidity may be reached in the drying operation. For example, in wet wash plants the goods are tumbled in a drying tumbler, such as the one here described, not only to break up the mass, but also to remove a portion of the water. With the present apparatus, the maximum temperature setting may be re duced and the de-odorizing period of such duration that when the hot air is cut off there will remain in the material a redetermined percentage of moisture whic may reater than the percentage of moisture othes dried for other subsequent laundry operations.

' Again, in drying woolen materials a lower temperature is desirable than for other materials to prevent injury to the wool. Control of the temperature maybe effected in different ways. For example, in Fig. 1,.the damper 21 is adjustably mounted by the set screw 22* on shaft 22 and therefore adjustable relative to the o crating link 24.

current to re Damper 21 may thereby e adjusted durin the drying operation so as to admit col air in small uantity to the circulating air duce its temperature to such a degree that it will not injure the material and will still be hot enough to liberate the moisture from the same.
